Feosol Complete with Bifera is a patented, high-potency formula that contains two forms of iron: heme and non-heme. Heme iron is animal-based, like the iron in steak. Non-heme iron includes plant-derived iron, like the kind you find in spinach. Feosol Complete minimizes side-effects and enhances absorption. The presence of a heme-based iron enhances iron absorption, while our unique combination of iron minimizes side effects such as constipation and nausea – delivering the best of both worlds. One pill does it all. Take Feosol Complete once daily, with or without food – no vitamin C required since absorption is enhanced when the heme form of iron is present. Unlike other iron supplements, Feosol Complete with Bifera provides both heme and non-heme in a single, small pill, so you have the flexibility to take it whenever you want. Feosol - the #1 pharmacist recommended iron supplement brand. 30 tablets
